The United Arab Emirates has thrown its support behind neighboring Saudi Arabia's decision to label the Muslim Brotherhood a terrorist organization, increasing Persian Gulf Arab pressure on the Islamist group.

Saudi Arabia listed the 86-year-old Brotherhood along with several other groups, including al Qaeda affiliates, as terrorist organizations on Friday. Those who join or support the groups could face five to 30 years in prison under the new Saudi policy.

The gulf moves against the Brotherhood follow an Egyptian decision to label it a terrorist organization in December. The move by the military-backed interim government in Cairo comes amid a crackdown on the group following its July ouster of the country's first elected president, the Islamist Mohammed Morsi.

The Western-allied United Arab Emirates said it will cooperate with Saudi Arabia to tackle "those terrorist groups through liquidating all forms of material and moral support."

Saudi Arabia and the United Arab Emirates, the two largest Arab economies, have increasingly clamped down on the Brotherhood in the wake of the Arab Spring uprisings.
